Feature Description
Remote On/Off
The Austin MicroLynx
feature an On/Off pin for remote On/Off operation of
the module. If not using the remote On/Off pin, leave
the pin open (module will be On). The On/Off pin
signal (Von/Off) is referenced to ground. To switch
module on and off using remote On/Off, connect an
open collector pnp transistor between the On/Off pin
and the V
When the transistor Q1 is in the OFF state, the power
module is ON (Logic Low on the On/Off pin of the
module) and the maximum Von/off of the module is
0.4 V. The maximum allowable leakage current of the
transistor when Von/off = 0.4V and V
10μA. During a logic-high when the transistor is in the
active state, the power module is OFF. During this
state VOn/Off =10 - 14V and the maximum IOn/Off =
1mA.
Figure 27. Remote On/Off Implementation
Remote On/Off can also be implemented using open-
collector logic devices with an external pull-up
resistor. Figure 27a shows the circuit configuration
using this approach. Pull-up resistor, R
configuration should be 68k (+/-5%) for proper
operation of the module over the entire temperature
range.

Overcurrent Protection
To provide protection in a fault (output overload)
condition, the unit is equipped with internal
current-limiting circuitry and can endure current
limiting continuously. At the point of current-limit
inception, the unit enters hiccup mode. The unit
operates normally once the output current is brought
back into its specified range. The typical average
output current during hiccup is 2A.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout
limit, module operation is disabled. The module will
begin to operate at an input voltage above the
undervoltage lockout turn-on threshold.
Overtemperature Protection
To provide over temperature protection in a fault
condition, the unit relies upon the thermal protection
feature of the controller IC. The unit will shutdown if
the thermal reference point T
exceeds 140
not intended as a guarantee that the unit will survive
temperatures beyond its rating. The module will
automatically restarts after it cools down.
